remedial restraint posts to walkway balustrade walls

The subject building is part of an estate of 1930’s style low-rise blocks of apartments in West London of conventional brick and filler joists built construction with open access decks and private balconies.


Defect

 

This very large building is curved with convex walkway balustrade walls,  outward stepping out at the base of the walls together with outward leaning and cracking of the brickwork and coping stones to the walkways balustrade walls was reported and noted.

 

Discussion

 

Action Wall Ties investigated the defects and reported that the causation was found to be due to seasonal moisture, thermal expansion and contraction i.e. hygro-thermal movement. Bearing in mind the length of brickwork balustrade walls have been constructed without the benefit of any expansion joints. The expansion has pushed the walls outwards, in some cases stepping out the base of the wall and the wall to lean outwards.

Solution

 

Action Wall Ties remediation works are designed to provide a cost effective long term solution ameliorating the defects noted that retains the existing appearance with the minimum effect to the occupants and impact on the environment  


To stabilise the balustrade wall Action Wall Ties completed remediation involving cutting expansion (movement) joints and the design fabrication and  fixing of restraint posts.
